It is not clear from your message whether this is a new KAT and has never 
worked, or whether it used to work and has failed.

If it is the latter, there is some detailed voltage information in the 
manual that might help. It could be a power metering failure. Happened to 
me, I lost both diodes in the directional coupler, giving low power 
readings, but high current and high actual power on an external meter.
